Comment #4 on issue 3970 by avichal@gmail.com: A bug on the degree
function

Currently the degree() function converts the expression into a polynomial
class and then calls the class' degree method.
I was thinking of the following

Hi,
I think that solution 1 is better, constants don't depend on any generator

degree(0) == -oo has already been fixed.
I agree it would be nice for degree to work if there are no symbols in the
expression.

Hi, indeed, the gen parameter may have caused the error.
To my mind, it would be clever that degree works the way you propose.
(and maybe with a degree(0) =

Is this issue still valid?
I get the following result: -
In [7]: degree(sympify(1), gens=x)
Out[7]: 0
Note that the original poster wrote gen=x instead of

It works if you pass a Poly (though we currently have the stupid -1
convention for 0 instead of -oo).

The function raises an exception on constants while it should answer 0 (and
even -oo on Zero in input)
